Problem

In JSM, we have two servicedesk APIs 

• one is for storing temporary files locally on a node
• and another one is for adding those temp attachments created via above API call to a customer request. This API call will fail with "Source file does not exist" error when it hits a different node.

Both servicedesk APIs are using methods under TemporaryWebAttachmentManager provided by jira-api-10.2.0 plugin. The methods we used

• createTemporaryWebAttachment
• convertTemporaryAttachments

Suggested Solution

Can we extend TemporaryWebAttachmentManager to have abilities on saving files to a shared home folder, which can later be accessed when calling convertTemporaryAttachments method.
